Welded pipe forming production line

Abstract

The invention discloses a welded pipe forming production line which comprises a guide leveling section, a forming section, a welding section, a welding seam post-processing section and a sizing section, a plurality of forming gantries are arranged on the forming section, a first upper carrier roller and a first lower carrier roller are arranged on each forming portal, and the first upper carrier rollers and the first lower carrier rollers are connected to a first reduction gearbox through a first transmission shaft. The first reduction gearbox is connected with an independent first motor; the welding seam post-processing section is provided with a plurality of extrusion devices; and the sizing section is provided with a plurality of sizing gantries. The first reduction gearbox of each forming gantry is driven by the independent first motor, and a sizing rack of each sizing gantry is driven by an independent second motor, so that the production efficiency of the whole forming production line is improved; the motors of all the gantries are mutually independent, when one of the motors breaks down, the work of other gantries cannot be affected, the waste length of welded pipes is reduced, raw materials are saved, and the cost of the raw materials is reduced.

Description

technical field [0001] The invention relates to the field of steel pipe manufacturing and production equipment, in particular to a welded pipe forming production line. Background technique [0002] Welded pipe is welded steel pipe, which is a steel pipe made of steel plate or strip steel after being crimped and welded. In the production process of welded pipes, steel sheets or strips often need to be rolled through several, a dozen or even dozens of rolls before they can be formed. value. The process flow of welded pipe is generally: raw material uncoiling - flattening - end shearing and welding - looper - forming - welding - removing internal and external burrs - pre-correction - post-processing of welds - sizing and straightening - flaw detection - cutting - inspection - upper Oil - Final Inspection - Packing - Shipment. [0003] The forming section of the high-frequency welded pipe production line is usually equipped with several forming gantry, and the pressing roller...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the shortcomings of the above-mentioned existing welded pipe production line, such as low production efficiency, large raw material waste, and high raw material cost, the applicant provides a welded pipe forming production line with a reasonable structure, which has high production efficiency, saves raw materials, and reduces raw material costs.
